Rogers brands 2015 Giro his toughest Grand Tour

Tinkoff-Saxo rider Michael Rogers has labelled this year's Giro d'Italia as the toughest yet and there are still 12 stages left of the first Grand Tour of 2015.

Rogers' team leader Alberto Contador leads the field by three seconds after the first nine days of the race, with the Australian bemoaning the gruelling terrain for already taking its toll within the peloton.
